2. Africa in world mining geography

Iron ore deposits can be found, although in relatively small quantities, in many other countries: Tunisia, Morocco and Egypt north of the Sahara, Niger, Nigeria, Mozambique, Swaziland and Tanzania to the south. South Africa, with a third of actual resources, and Liberia, Libya, Mauritania and Algeria appear as the main iron ore countries, but

The iron ore deposits of El-Bahariya oasis, Egypt

Iron ores occurring mainly in lower Eocene limestone at Gebel Ghorabi, in the northern part of the oasis, include an oolitic type consisting essentially of goethite, a vesicular type containing hematite with pyrolusite and psilomelane, a hard, dark brown type consisting of goethite and hematite with some pyrolusite, and a low-grade limonitic type.

9 Ore Deposits and Economic Minerals Mineralogy

Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, or sedimentary. 9.1 Mineral Commodities 9.1.1 Mineral Resources. Earth gives us many mineralogical resources, also called mineral commodities. Fewer than a dozen minerals and eight or nine elements dominate the crust

MOROCCO : ONHYM tests its luck with Seferif iron ore

2017-11-14  The four deposits identified on the concession, Wixane, Axara, Imnassen and Setolazar, are reported to contain a measured and indicated resource of more than 26 million tonnes of iron ore. In 2015, ONHYM had already tried to sell these mines by, unsuccessfully, opting to privatise its wholly-owned unit Seferif.

IRAN/GUINEA : Tehran hopes to capitalise on

1 天前  Conakry's other partners, such as Morocco (AI, 22/09/21) and the United Arab Emirates, are also at loggerheads with Iran. Iran hopes that its request for an iron ore research permit might now be considered favourably, given that the Guinean putschists are being held at arm's length by the international community and are looking for allies.

Cobalt—Styles of Deposits and the Search for Primary

2017-11-30  None of these deposit types show direct links to mafic-ultramafic rocks; the deposits may result from crustal-scale hydrothermal systems capable of leaching and transporting cobalt from great depths. Hydrothermal deposits associated with ultramafic rocks, typified by the BouAzzerdistrict of Morocco, represent another type of primary cobalt deposit.

What Are The Major Natural Resources Of Algeria?

2019-6-13  Algeria has rich iron ore deposits, particularly in the southwestern region of the country. During the 1970s, Algeria produced as much as 4.2 million tons of iron annually. As of 2016, the iron reserve in Gara Djebilet had an estimated 2.5 billion tons of iron ore. Algeria's iron is both exported and used locally in the metallurgical industry.

Remote sensing techniques using Landsat ETM+ applied

2012-10-30  Actually, the iron ore deposits located in Djebilet are not highlighted by the PC3 image. The use of the PC6 image is avoided because, due to the high noise, it does not clearly highlight the areas characterised by ferrous minerals. According to the present study, the 4/1 ratio is the most useful band ratio for detecting iron oxides.
